Health Secretary Yvette Cooper said she was “profoundly sorry” on behalf of the government for the failures set out in the report.
She said she had asked officials to “urgently develop plans” for cot-cams in neonatal units, and that the government would consider Thirlwall’s other recommendations in full.
Cooper also said she expected NHS leaders across the country to uphold their safeguarding responsibilities.
She plans to meet Thirlwall, who made 17 recommendations including restricting access to insulin, later this week to discuss the inquiry in more detail.
Thirlwall was clear that her inquiry was not an investigation into Letby’s guilt, which some supporters of the jailed nurse still contest.
A number of Letby supporters gathered outside Liverpool Town Hall to voice their concerns over her conviction, calling for her release, before Thirlwall delivered her inquiry findings.
Now 36, Letby is serving 15 whole-life prison terms for murdering seven babies and attempting to murder seven more.
She was convicted in 2023 and has been denied permission to appeal against her convictions twice.
